In a November 19 memo to the Environmental Protection Agency’s regional offices, assistant administrator for air and radiation Gina McCarthy said that the agency will review state air pollution plans to ensure that they can meet emissions reduction goals even though they may no longer be able to rely on significant reductions in emissions of SO2 and NOx under the Cross-State Air Pollution Rule. A federal appeals court vacated the cross-state rule in August, leaving in place the 2005 Clean Air Interstate Rule, and the agency will act in accordance with the decision while it appeals the ruling.
